They pass massive bills not knowing what they contain, and even worse amend them at the very last second with verbal votes to amend containing god knows what. During the budget bill McConnell just rammed through what is effectively a hemp ban amendment which no one seemed to know about up until the point Massie forced a vote to on whether to take it back out, at which time a large number of people who had at all times been vehemently against anything like a hemp ban bizarrely voted the exact opposite for reasons that they've made almost entirely opaque.
None of it makes any fucking sense. The fact things wrapped up in mega bills basically breaks any semblance of a democratic system; either you vote for the entire package, or the entire government breaks, or your competitor gets to slam you for hating on the children because you had to defund them in order to avoid doing some other terrible thing.
It's broken because for the past ~70yr there was scant if any scrutiny of what they were up to because half or more of the country "trusted the process" (or whatever you want to call it) if not the people. They were free to write, write, write and expand, expand, expand with no serious pushback and so of course a lot of it was garbage. When you write loans to anyone with a pulse too many of them are gonna be sub prime. When you just let legislatures legislate and bureaucracies bureaucrat too many of the results are gonna be shit. And now that bill is coming due.
